Study of Rare and Forbidden μ- and π-Decays

  • R. Engfer
Conference paper


The standard Glashow-Salam-Weinberg model [1–2] combines weak and electromagnetic interactions on the basis of a spontaneously broken SU(2)LxU(1) symmetry. The experimental verification [3–5] of the existence of its most noticeable prediction, the W and Z bosons led to profound trust in this model as the correct description of electroweak processes at “low energies” up to tens of GeV. The phenomenon of maximal parity violation, i.e. the V-A structure of weak interactions and the masslessness of neutrinos is built into the theory by assigning lefthanded fermions to SU(2) doublets and righthanded ones to singlets and requiring lepton number conservation.
